A well pipe top enclosing pipe cap is provided that has two pivotally interconnected half cylindrical concave pipe end enclosing halves pivotal from an open state to a closed state. The half cylindrical concave halves made of iron, or steel, have half circle enclosing tops and inwardly extended projections at the bottoms that come into upward motion limiting engagement with the bottom of the well pipe top end boss holding the well pipe cap in place in the closed state. In the closed and locked state a cylindrical lock element on one cylindrical concave pipe end enclosing half is mounted for being in alignment with and between two cylindrical lock elements on the other pipe end enclosing half, and an "L" shaped lock rod element is inserted through the aligned lock elements. The top branch of the lock rod element is lowered into a "U" shaped bracket welded in place on the top of one of the half circle enclosing tops and a padlock is locked in place with a portion of its hasp loop extended through aligned openings in opposite sides of the "U" shaped bracket. A lifting handle is welded on the top of the other semicircle enclosure top.
